To all whom it may concern:

Be it known that I, WVILLIAM VVneLEY, a citizen of the United States,resldlng at Knoxville, in the county of Knox and State of Tennessee,have invented a new and useful lmprovementin Loading-Machines, of' whichthe following 1s a speclficatlon, ref- 7 erenco being had totheaccompanying draw-v While the machine is primarily intended for' use insuch workings, it may also be used in open situations for. the loadingand digging of coal, ores, gravel, sand, earth, and other loosematerials.

The improvement may be embodied in a variety of forms. In the particularform herein described, the invention is embodied in a machine comprising(1) a frame mounted upon supporting wheels for the moving of the machineto and from the material to be loaded; (2; an endless conveyer extendinglengthwise of said frame and high enough at the rear end to discharge ona wagon, car or otherwise; (3,) a shovel or scoop sup ported at'thefront end of said frame and so controlled as to move forward with itsnose upon the floor or ground and take a load, lift the load and move itrearward and discharge it upon said conveyer.

Any suitable power isto be provided for operating the conveyer and thescoop or shovel. In the form illustrated by the draw ings, an electricmotor is mounted upon said frame to furnish such power.

In .the accompanying drawings, Figure 1 is a side elevation of anapparatus embodyline 33 of Fig. 2, looking in the direction of ing myimprovement; Fig. 2is a plan of the same structure, DOItIOllS beingbroken away; F1g. 3 IS a longitudinal uprlght section on the the arrow;Fig. 4: is a transverse uprightsection on the l1ne 4-4 of Fig. 1,looking in the direction ofthe arrow; Fig.5 is a section on the line 5-5.of Fig. 2, looking in the direction of the arrow; Fig. 6 is a detailplan of one of the rear corners of the rear conveyer;- Fig. 7 is ahorizontal section on the line 77 of Fig. 1; Fig. 8 is a detail, uprightsection of the scoop-supporting mechanism.

Referring to saiddrawings, 1, 1 are lower side rails of the frame.Therea-r ends of said rails are connected by a cross-rail, 2, and thefront ends of said rails are connected by a cross-rail, 3. Saidrails'are also connected by intermediate crossrails, 41, 5,- 6, and 7.From the rear end of each side rail rises a corner post, 8. Said'postsare inclined toward each other. (see Fig. 5). On the front end of eachof said side rails is a plate-form corner post, 9. A brace, 11,

extends from the up er end of each rear corner post, 8, oblique ydownward and forward to the adjacent lower side rail, 1; and a similarbrace, 12, extends fromeach'corher post, 9, obliquely downwardandrearward to the adjacent lower side rail, 1. To the front portion of thelnner face of each corner post,-9,- is riveted or bolted an uprightchannel piece, 13. Above andparallel to each side rail, 1, is an upperside rail, 10, having its rear end secured to the adjacent'corner post,8, and having its forward end secured to the inner web of said channelpiece, 13, said upper rails being nearer to each other than are saidlower rails. And each upper side rail is secured to the channel piece,13, only a little way above the front end of the lower side rail andextends thence obliquely upward and rearward and then forms an angle andextends rearward to the height of the rear corner post, 8, and extendsthence rearward any desired distance beyond the rear corner post. Fromthe angle in saidupper side rail, a supplementary side rail, 14, extendsforward horizontally to the inner web of said channel piece, 13, and issuitably secured thereto. And each such-supplementary side rail, 14, isjoined to the main up per side rail, 10, by means of a gusset plate, 15.Each upper side rail is of channel form, the flanges being turned inwardto form ways for carrying the conveyer belt, as will be hereinafterdescribed.

' In line with each upper side rail is a bearing, 16, in said channelpiece, 13, and a transverse horizontal shaft, 17, rests in saidbearings. At the extreme rear end of each upper siderail, 10, is abearing, 18, and a transverse shaft, 19, rests in said bearings.

On saidshafts, 17 and 19, are sprocket B'y' inclining the forward theshaft, 19, and, through the latter, the

conveyer belt. Said sprocket chain passes over two idle wheels, 23 and24, and around a sprocket wheel, 25, on a counter-shaft, 26, mounted in"bearings, 27, on the frame of the-electric motor, 28, which motor frameis seated upon the intermediate cross-rails, 4 and 5. Power is im artedfrom said motor to said countersha t, 26, by means of a spur gear wheel,29, on the motor meshing with a larger spur gear, '30, on'said shaft. Oneach upper side rail,'10, are mounted outward directed brackets, 31,supporting sloping side plates, 32, which form the sides of a trough ofwhich the conveyer belt is a. traveling bottom.

We now come to a description of the scoop or shovel and the mechanismfor supporting and actuating the same. 1 To the front face of eachchannelpiece, 13, is bolted or riveted an elbow piece, 33, the uprightarm of said elbow piece being directed upward.- A little way below saidpiece, 33, is a horizontal member, 34, separated at each end from theelbow piece, 33, by spacing blocks, 35. Through the front spacing blockand the adjacent ends of the member, 34, and the elbow piece, 33, passesa binding bolt, 36; and a bolt,,37, passes upward through the rearendofthe member, 34, and the adja- 1 centspacing block, 35 and is tappedinto the adjacent portion of the elbow piece, 33. In this way arectangular opening constituting a slide-way, is formed for a slidingblock, 38. Each such block has a groove, 39, above to receive the elbowpiece and a groove, 40, below for receivingthe' horizontal member, 34.By this. means, said blocks are effectively confined and limited to ahorizontal movementparallel to the length ofthe machine, and suchmovement is without rotation of-said block.

' At the inner side of each member, 34, (the side directed toward theother member, 34)

a rigid ear,'41, extends downward from the "adjacent slide block, 38;,and in each such ear is a horizontal transverse bearing, :42. Atransverse horizontal shaft, 43, rests in I said bearings, its endsprojecting through said bearings and supporting segmental gears, 44.rectangular bar, 45, has journals, 46, at each end extending throughbearings, 47, in the slide blocks, 38, and projecting -far enough tosupport segmental gears,

given a partial rotation upon the axis of said shaft,45. But suchmovement is only a partial rotation limited by the extent of engagementbetween the segment gears, 44 and 48approximatel a-half circle. Whensaid segment gears iscngage, the shovel falls back to its originalposition by gravity. In addition to said partial rotation upon the axisof the shaft or bar, 45, said shovel reciprocates horizontally by thereciprocation of the .slide blocks, 38, whereby the shaft or bar, 45, iscarried forward and backward. Said blocks .are reciprocated by mechanismas follows: Adjacent one of the segment gears, 44, on the shaft, 43, atthe rear of the scoop is a bevel gear, 51, surrounding ;said shaft; andsaid bevel gear meshes with another bevel gear, 52, on a telescopingshaft, 5.3,whichis parallel to the length of the machine and rests atits front end in a bearing, 54, in the adjacent channel piece, 13,-andat its rear end in a bearing, 55, and is loosely surrounded at its rearend by a bevel gear, 56, meshing with a bevel gear, 57, on acounter-shaft, 26, adjacent the electric motor, 28. A clutch, 56, on theshaft, 53, serves to engage the bevel gear, 56, to. said shaft (Fig. 2The bevel. gear wheel, 52, and the portion of the shaft, 53, theretoattached are held in position by a bearing, 62, in a curved rearwardextension of the ear, 41, on the adjacent slide block, 38. By means ofsaid gears and telescoping shaft, the shaft is continuously rotatedclockwise as viewed in Figs-1 and 3, and with each rotation of saidshaft the segment gears,

- 44, on said'shaft engage the segment gears,

48, onthe shaft or bar, 45, and impart a partial rotation to the latter,as already described. On each end'of the shaft, 43, is a rigid crank,58, the outer end'of each of which is coupled at 60 to one end of alink,

.59, the other end of which link is journaled at 61 tothe frame of themachine. Said link is therefore free to oscillate in an up right planewith the point, 61, for a center; and said links restram the rotation ofthe cranks, 58, to such extent and in such manner as to cause a reactionupon the shaft, 43, and through the latter upon the slide blocks, 38, tocompel the latter to move horizontally between the horizontal members,34, and the elbow piece, 33. In other words, said cranks tend toimpartto. the shaft, 43, an orbital movement as a reversal of theorbital move-' ment of the outer ends of the cranks; but

said orbital movement is modified to a .reciprocatory movement by saidhorizontal member, 3t, and the elbow piece, 33, the oscillation of thelinks, 59, compensating for the absence of the orbital movement of saidshaft and the. consequent rotation of the outer ends of the cranks upona fixed line. During such reciprocatory movement of the slide blocks,.38, the telescoping shaft, 53, shortens and lengthens to the extent ofthe reciprocation of said blocks. l

' The purposeof the bodily reciprocation of the scoop is to bring thenose of the scoop in front of the material beneath which the scoop is topass. The movements are so timed as to bring thescoop to its rearwardlimit when the nose of the scoop reaches the low portion of its orbit,and to bring said nose to the high part of its orbit when the rear limitof reciprocation is reached, in order that the'scoop may then be sotilted backward as that the material thereon will move rearward out ofthe scoop upon the conveyer. I

Provision is also made for propelling the machine by the power of theelectric motor,-

28, to take the machine from one working place to another or to propelthe machine forward for its work. For this purpose, a counter-shaft, 63,is seated in bearings, 64, parallel to the countershaft, 26, andprovided with a spur gear wheel, 65, meshing-with a spur gear wheel, 66,on said counter-shaft,

, 26-. On the counter-shaft, 63, is a reversing gear member, 67,comprising two bevel gears directed toward each other, said member beingkeyed for sliding upon said shaft and to rotate therewith. A bellcranklever, 68, engages an annular groove, 69, 'on said member, 67whereby said reversing member may be reciprocated by the operator of themachine.

A shaft, 71, is mounted in bearings, 72, parallel to the length of themachine and on the rear end of said shaft is a'bevel gear, 70, standingbetween the bevel gears of the reversing member, 67. said shaft is aworm, 73, which. engages a worm gear wheel, 74, on the axle, 75, andsaid axle rests in the supporting wheels, 76, and said wheels rest onthe desired form of track. The shaft, 63, and the reversing gear member,67, receive motion from the motor, 28, and either one of the bevel gearsof said member may be made to engage the bevel gear wheel, 7 O, or

said reversing member may be put into such the shovel and the conveyerand the forward On the front end of round or any suitable car, so thatthe scoop may be given a sidewise reach for the purpose of operatingover a wider area than is possible when no lateral movement is made.Such a car and jib are shown in my application Serial N 0. 381,624,filed in the United States Patent Oflice July 1, 1907.
